Hey you guys talk about warming up when running forged pistons....how much time are you talking about? 30 seconds? 3 or 4 minutes?

I warm all my motors up forged pistons or not for 3-5mins before getting on the throttle hard.

Well if I remember that night correctly, YOU were the only one to have done this more than one time....so I hold you fully responsible.
And I will be taking the cylinders to the shop soon....

How important is this for a recreational motor.....is this only used for a race motor?

awesome thread.... I have always used Pro-X w/ great success.
I don't like to even think or worry about warming up, so they are perfect for me... As far as weight difference goes... not a factor in a surf boat... IMO

Wsm
I've run WSM's in my 650 for 2 seasons without a problem. I originally had the cylinders bored at just about .003" clearance I believe. I think my machinist told me .003" for cast and .005" for forged. It's been a while so I'm not sure if I'm getting the clearances right... they both seem to be pretty tight to me I think at .005 it would be hard to slide in.
Anyways I had no problems for 2 yrs at which time I tore it down to build a 701 and it still looked good inside. Only issue was before installation had to send one piston back because the ring wouldn't fit due to a misinstalled ring end-pin.
In my 701 I ran Wiseco's which had a lot more scuffing on the sides when I took it apart to rebuild due to detonation damage. Got a little too cocky and filled it up with regular on almost 190psi cranking. Made it about 1/2 mile.
I have a new 84mm WSM in the garage that I could weigh if I had a scale. maybe I can bring it to the post office and ask them.

When cast pistons are over heated, the skirts become very brittle. They have been known to fall apart into many pieces and will damage internal engine components.

I have been there and done that with WSM pistons.
Never again, ANYTHING but wsm pistons.
proX, wisecoe, art,sudco.
ANYTHING but WSM
I posted some pictures in a thread on PWCyesteryear, showinf the differences in prox and wiseco pistons.

Ya, CRUMBLE into tiny pieces and easily suck through your cylinder ports and ruin your top end along with your crank. Wheras a forged is stronger and if it does break it will only be a piece or 2 and wont make it to your top end to destroy it. Ever seen a cast crumble like a cookie? not pretty!!:frown:

What pistons to use ? And where to buy them?
Hey Guys,
I'm new to the jetski/jetboat world. I recently sold my ski and bought a 96 Seadoo Challenger. I need a top end rebuild kit. I was gonna buy the one on ebay with WSM'S, or SBT, but then I came across this thread when I searched wsm pistons.
Any suggestions on what kind and where I should buy ? Its a single 787 engine with 1.00 pistons now. My buddy owned it and had it bored out some. I don't know much more about it or about ski/boat engines.
I'm looking to get these parts asap. The boat sat last summer and I really wanna use it this summer. I have a seado mechanic ready to put it back together, soon as I get this kit.
Any help would really be appreciated/needed !!
Thanks

I'm doing the piston search game right now for my blaster. The cylinders are still on the stock bore but I would want to go up at least .25mm and wiseco well they start with over bores at .50mm, why lose a whole bore? Granted I have run wiseco's in the past exclusively in dirtbikes both 2 and 4 stroke, and have never had a problem. But going to Pro-X's for saving a bore on the cylinders is more appealing to me. Wouldn't one think that adding life to a cylinder that isn't really chewed up is better?
But on the flip side if your cylinder is scraped up good from a ring melting or cold seize. Then I will admit going bigger might be your only choice.

Ive used WSM piston kits dozens of times on my own and customers machines. I have used the Standard and Platinum series. Never a problem once and they look like quality parts. I see the reviews on WSM were not so good a few posts back. Well maybe they changed something in production since 2006 or you just had a problem that would have damaged any brand piston.
As for SBT piston quality? They are decent. They are lighter then the WSM and are NOT forged (cast/hypr). They would not hold up well under less than ideal conditions and I would avoid them. ProX pistons could be considered on par with the WSM Platinum series.
My experiences are mostly on Yamaha and Seadoo.
